EFFECTIVE TODAY, THURSDAY SEPTEMBER 6, 2012, THE NATIONAL WEATHER
SERVICE (NWS) WILL ADD A NEW FLOOD INUNDATION MAP TO THE ADVANCED
HYDROLOGIC PREDICTION SERVICE (AHPS) WEB PORTAL FOR THE SADDLE RIVER
AT LODI, NJ. THIS INUNDATION MAP WILL PROVIDE DATA FOR THE STATE OF
NEW JERSEY AND WILL BE ASSOCIATED WITH A UNITED STATES GEOLOGICAL
SURVEY (USGS) RIVER GAGE REPRESENTING A NWS FORECAST POINT. THE
MAPPING WILL EXTEND BOTH NORTH AND SOUTH OF THE GAGE SITE.

INUNDATION MAPS PROVIDE INFORMATION ON THE SPATIAL EXTENT AND DEPTH
OF FLOOD WATERS IN THE VICINITY OF NWS RIVER FORECAST POINTS. USERS
WILL BE ABLE TO DISPLAY FLOOD INUNDATION MAPS FOR VARIOUS LEVELS
RANGING FROM MINOR FLOODING THROUGH AND/OR ABOVE THE LARGEST
OBSERVED FLOOD.

FLOOD INUNDATION MAPS, COMBINED WITH RIVER OBSERVATIONS AND NWS
FORECASTS, ENHANCE THE COMMUNICATION OF FLOOD RISK, PROVIDE USERS
WITH ADDITIONAL INFORMATION TO BETTER MITIGATE THE IMPACTS OF
FLOODING, AND BUILD MORE RESILIENT COMMUNITIES.

THIS FLOOD INUNDATION MAP AND ASSOCIATED GEOSPATIAL DATA
(SHAPEFILES) CAN BE ACCESSED THROUGH THE AHPS PORTAL (USE LOWER CASE
LETTERS):

THESE INUNDATION MAPS WERE DEVELOPED BY THE U.S. GEOLOGICAL SURVEY
AND NEW JERSEY DEPARTMENT OF ENVIRONMENTAL PROTECTION. THEY ARE MADE
AVAILABLE ONLINE THROUGH CONGRESSIONAL AND NOAA GRANT SUPPORT TO THE
PASSAIC RIVER COMMISSION AND NOAA-NWS.
